Description

TECHNICAL FIELD

[0001] The utility model relates to computer shell paint spraying field, concretely is a computer shell processing paint spraying equipment. BACKGROUND

[0002] The computer shell processing paint spraying equipment is a series of devices for paint spraying treatment on the surface of the computer shell. The main purpose of these devices is to make the computer shell obtain uniform, beautiful and protective paint layer.

[0003] The patent number CN221268616U, in the computer shell processing paint spraying process, the paint in the paint spraying box is prone to surface skinning phenomenon, paint skinning is mainly due to its contact with air, solvent gradually volatilizes, leading to the relatively high concentration of resin, pigment and other components on the surface of the paint, and then forming a solid skin layer, paint skinning will bring many hazards, the properties of the paint in the skin part change, the viscosity increases, and the component ratio of the paint in the internal non-skin part is unbalanced. When the skin mixes into the paint, it will make the fluidity of the whole paint worse, affect the normal atomization effect of the paint spraying gun, cause the size of the sprayed paint particles to be uneven, and the thickness of the coating formed on the surface of the computer shell to be inconsistent, which seriously affects the flatness and uniformity of the coating. In order to prevent surface skinning, the paint spraying box usually adopts the way of stirring shaft. The stirring shaft continuously rotates to continuously disturb the surface of the paint and destroy the skin structure that may be formed on the surface of the paint, thereby delaying the occurrence of skinning to a certain extent. However, this method has obvious disadvantages. When the stirring shaft continuously works as the paint level in the paint spraying box decreases, air bubbles are easily mixed into the paint due to the rotating action of the stirring shaft. The paint level and the stirring shaft blade are at the same level, the stirring shaft blade breaks the upper surface of the paint, and a large amount of air is rolled into the paint to form a large number of air bubbles of different sizes. These air bubbles will seriously affect the spraying quality of the computer shell during the spraying process. When the air bubbles burst after being sprayed with the paint onto the surface of the computer shell, they will leave pits, pinholes and other defects on the coating, damage the integrity and flatness of the coating, and make the surface of the computer shell lose the smooth and uniform appearance effect. At the same time, it also reduces the protective performance of the coating and cannot provide reliable protection for the computer shell, affecting the overall quality and service life of the product.
